Murderer by passion

The story of a psychopath.
Karl Liebknecht - the main character of this novel - loses his young wife and parents on the same day in a car accident caused by a drunk Yugoslav lorry driver. Liebknecht, a conscientious case worker at the social welfare office, withdraws more and more into himself until one day he unintentionally kills a young Yugoslavian girl. He tells himself that she was 'only' a member of the same people who had killed his family. Liebknecht comes into contact with neo-Nazi circles and begins to hunt down foreign drug dealers and prostitutes. Initially, the victims are merely beaten up - but later Liebknecht, who has begun to steel his body through strength training, switches to locking the victims in his cellar and then murdering them. Liebknecht kidnaps the wife of Inspector Werner, who suspected the real perpetrator very early on but was unable to produce any evidence, and makes her play sex games with three Africans in front of a hidden camera. Liebknecht sends the recorded videos to the press and police and begins a game of cat and mouse to break free from the boredom of daily monotony. The inspector's assistant detective is also kidnapped and murdered. Liebknecht transforms from a staid civil servant into a sarcastic monster, but loves his black housekeeper Agatha, who supports him wholeheartedly in his perverse misdeeds....
